Vehicle Key Recognition for Personalized Car Welcoming Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle welcoming technologies lack personalization and efficiency in recognizing and responding to different vehicle keys, leading to a uniform welcoming experience for multiple owners, which does not meet individual preferences.
Innovation Solution
A method and apparatus that recognize the ID of a target vehicle key through wireless communication, using a public-private key pair for secure identification, and perform customized welcoming actions based on preconfigured manners associated with each key, considering distance, ambient volume, and orientation to provide personalized welcoming strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a uniform welcoming function is implemented for all vehicle keys, then the system complexity is reduced and ease of manufacture is improved, but the adaptability and personalization for different users deteriorate
Solution Approach 1:
The patent segments the welcoming function by creating separate welcoming manner configurations for different vehicle keys. Each key ID can be associated with its own customized welcoming manner, allowing the system to provide personalized experiences for different users while maintaining a modular structure that doesn't significantly increase overall system complexity
Solution Approach 2:
The patent applies local quality by allowing different welcoming manners to be configured for different vehicle keys. Instead of a uniform welcoming function for all keys, the system enables localized customization where each key can have its own specific welcoming actions, lighting patterns, and pedal extensions tailored to individual user preferences
2Measurement precision
If multiple ranging methods are used to detect distance, then the measurement precision is improved, but the use of energy and device complexity increase
Solution Approach 1:
The patent implements a dynamic ranging strategy where the system first uses a first ranging method to detect initial distance, and only when the distance is less than a second threshold does it switch to a second ranging method with higher precision. This dynamic adaptation of measurement methods based on current conditions optimizes energy consumption while ensuring sufficient precision when needed
Solution Approach 2:
The patent performs a preliminary distance detection using the first ranging method before initiating more energy-intensive operations. By first checking if the vehicle key is within a certain range using a lower-power method, the system avoids unnecessary activation of high-precision ranging systems, thereby conserving energy while maintaining measurement accuracy when required
3Adaptability or versatility
If welcoming actions are performed based on multiple conditions (distance, volume, voice instructions), then the adaptability and user experience are improved, but the response time and operational efficiency may deteriorate
Solution Approach 1:
The patent performs preliminary detections of distance and ambient volume before processing voice instructions. By checking these conditions in advance and only proceeding with voice recognition when conditions are favorable, the system reduces overall processing time while maintaining high adaptability to different user scenarios
Solution Approach 2:
The patent implements a staged welcoming process where different actions are performed in sequence based on detected conditions. The system periodically evaluates distance, volume, and voice instructions at appropriate stages, allowing complex multi-condition logic to be executed efficiently through structured periodic checks rather than simultaneous processing
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables personalized welcoming experiences for multiple vehicle owners by configuring dedicated welcoming manners for each vehicle key, enhancing user convenience and satisfaction while maintaining operational efficiency and safety.
Implementation Method 1
detecting a first distance between the target vehicle key and the vehicle with a first ranging method, and in response to that the first distance is less than a second threshold, detecting a second distance between the target vehicle key and the vehicle with a second ranging method
Data Source
AI summary
A method for controlling a vehicle welcoming to a user, includes: recognizing, by a processor of the vehicle, an identification (ID) of a target vehicle key; searching, by the processor, a correspondence for a welcoming manner corresponding to the ID of the target vehicle key, the correspondence comprising a plurality of IDs of a plurality of vehicle keys and a plurality of welcoming manners corresponding to the IDs of the vehicle keys; and controlling, by the processor, the vehicle to perform a first welcoming action in the welcoming manner.
